Why is my solar light not working?

One of the most common reasons why your solar light isn’t working is the wire between the solar panel and the battery. This wire is responsible for transferring the generated electricity from the solar panel to the solar battery — charging it in the process. If this wire is broken, then your batteries won’t charge no matter what you do.

Why is my solar panel not working at night?

This can also happen if there are nearby light sources which make the environment overly-bright at night. By shading your solar panel, you force your solar light to recognize that lighting levels are low and that it needs to give off light, allowing your light to start working again. 2. Check Your Batteries

What happens if a solar panel fails?
